That's exaclty what I think drew their attention - spirals and life - Fibonacci series and cell replication - the fossil of a burrowing worm

The question is whether the thing is 3 dimensional or an optical illusion - simply gravel lying across a regularly grooved but differently eroded surface -

Since the optics are known, the final images could be deblurred by known algorithms, if this rove were to have already ended - could be they're heavy into troubleshooting, coud be they're sitting on something nice, could be they're simply taking time off for Father's Day

oh well - it's probably not anything as interesting as that - I suppose we'll find out soon enough

best wishes,
